The Solar Chromosphere

Observations of the Sun in H-alpha


This is a series of observations of the Sun in the light of hydrogen (H-alpha at 656.3 nm) made with a small telescope (40mm aperture) and a narrow filter bandpass (~0.06 nm). Technical details of the telescope, filters, camera and observing technique are given on technical details page.

For each day on which observations were made, I show an on-band H-alpha image (haon), usually an off-band image (haoff: to show the continuum) and an active region map (armap) taken from the archive at http://www.solar.ifa.hawaii.edu/ARMaps/armaps.html.

Please note that the images are not precisely aligned with the AR Maps. As explained on the technical page, the images are usually taken with an altazimuth mount.
